C) 9 : 45 : 15 PM | D) 10 : 23 : 20 PM |

Explanation:

The watch gains 5 seconds in 3 minutes = 100 seconds in 1 hour.

From 8 AM to 10 PM on the same day, time passed is 14 hours.

In 14 hours, the watch would have gained 1400 seconds or 23 minutes 20 seconds.

So, when the correct time is 10 PM, the watch would show 10 : 23 : 20 PM

A) 90 degrees | B) 85 degrees |

C) 60 degrees | D) 45 degrees |

A) 16 deg | B) 80 deg |

C) 88 deg | D) 94 deg |

Explanation:

For ticking 6 times, there are 5 intervals.

so total time for 11 intervals = 11 x 6 = 66 secs.

A) 3:15 2/8 | B) 3:49 |

C) 3:49 1/11 | D) 3:51 |

Explanation:

On straight line means 180 degree angle.

180 = 11/2 min – 30 hrs

180 = 11/2 m – 30 × 3

180 = 11/2 m – 90

(180 + 90) 2 = 11 m

m = 540/11 = 49 1/11 minutes.
